7 Be it known that I, OLIVER GE RI sH, a

.citizen of the United States, residing ,at

Benicia, in the countyof Solano and State of California, have invented certain new and useful Improvements in Hide-Protector Attachments for Fleshing'Machines, of n H with the fleshing 7 cylinder.

The free ends of the frames 14 ride on and are guided by the shaft portions of the rubber roll 10, and the pinch roll 12 rests on and is guided by the upper surface of the free ends of the feed roll frames 14, as in Fig. 1.

The pinch roll when in operative position is forced into frictional contact with a conventional presser foot 16 normally pressed downwardly by springs 17. A water supply pipe 18 having a discharge head 19 extending parallel with and above the fieshing cylinder 2 supplies water to the hide as the same is being fleshed.

WVith the conventional construction of the fieshing machine above described is associated my present invention, consisting of a protecting means for the hide and the same includes a protecting guard or plate 20 disposed parallel With the fleshing cylinder 2 and guided at its ends to move in an upward inclination to lie between the rubber roll 10 and the fieshing cylinder 2 by suitable guide members 21, Fig. 3, carried by the end members 1. Fulcrumed to brackets 22 on the members 20, as at 23, are the upper ends of operating rods 24, terminating at their lower ends in split cam rings 25. The cam rings each encircle a guard operating cam 26 mounted respectively near the opposite ends of the shaft 3 and disposed with their peakat substantially right an les to the peak of the crank i.

larried by the discharge head 19 is a fixed guard 27 overlying the fieshing cylinder 2 and with the free edge of which the upper edge of the member 20 is adapted to contact, Fig. 1, when in its raised or operative position.

The shaft 3 is operated by any suitable manual mechanism and the rolls 12, 15 and 1.0 are caused to rotate in the direction of the arrows, by any suitable mechanism, power being imparted to the flashing cylinder- .2 in the direction of the arrow, Fig. 1.

The device operates in the followingmanner:

With the parts in position, as in Fig. 1, the hide to be fleshed is icked up in the center by the operator, midway between the head and tail; this causes the hide to fall into a folded position with the grain-side of the hide outward. The operator then places or throws the hide on the pinch roll 12 with a portion of it dropping onto con= tact with the rubber roll 9-. The upper fold is then thrown over into the machine, so that the hide will assume an unfolded position, which movement causes the grain side of the hide to be momentarily exposed and during such exposing, the guard 20 lying between the roll 9 and the cylinder 2 precludes the knives of the cylinder from injuring the face of the hide.

The edge of the hide which has been thrown over assumes a perpendicular position, and when the main body portion of the hide has been adjusted, the operator actuates the shaft 3, which causes the parts to move from a position in Fig. 1 to that in Fig. 2, the guard 20 exposing the fleshing cylinder 2 and the rubber roll 9 moving the hide to be engaged by the fieshing cylinder 2.

It will be observed that when the pinch roll, rubber roll. and feed roll are in the position indicated as in Fig. 1, that the guard 20 is elevated to preclude contact of the hide with the surface of the'cylinder 2, and that when the parts are moved into operative position, the guard 20 is lowered, as the protection of the hide is no longer required.

I claim 1. In combination with a fleshing machine including a fleshing cylinder, means for receiving a hide to be fleshed and for feeding the same to the cylinder, means for moving the hide receiving and feeding means into and from operative position relatively to the fleshing cylinder, a hide protecting guard, and means for moving the guard to overlie the cylinder.

2. In combination with a fleshing machine including a fleshing cylinder, means for receiving a hide to be fleshed and for feeding the same to the cylinder, means for moving the hide receiving and feeding means into and from operative position relatively to the fieshing cylinder, and a hide protecting guard movable between the cylinder and the hide receiving and feeding means. when the latter is in inoperative position.

3. In combination with a fleshing machine including a fieshing cylinder, means for receiving a hide to be fleshed and for feeding the same to the, cylinder, means for moving the hide receiving and feeding means into and from operative position relatively to the fieshing cylinder, a hide protecting guard adapted to overlie the cylinder, and a second hide protecting guard movable betw-een'thecylinder and the hide receiving means when the latter is in inoperative position.

4. In combination with a fieshing machine including a fleshing cylinder, means for receiving a hide to be fleshed and for feeding the same to the cylinder, means for movingthe hide receiving and feeding means into and from operative position relatively to the fleshing cylinder, a hide protecting guard, and means for moving the same between the cylinder and hide receiving means simul taneously with the movement of the latter into inoperative position.

5. In combination with a fleshing machine including a fleshing cylinder, means for receiving a hide to be fleshed and for feeding the same to the cylinder, means for moving the hide receiving and feeding means into and from operative position relatively to the fleshing cylinder, a hide protecting guard movable into and from operative position between the cylinder and hide receiving means, and operating means for the guard connected with the hide receiving means.

whereby said ard and hide receiving means alternate in their movement into operative position.

6. In combination with a fleshing machine including a fleshing cylinder,m'eans for receiving a hide to be fleshed and for feeding the same to the fleshing cylinder, and a hide protecting guard movable into operative position between the cylinder and the hide receiving and fleshing means to preclude contact of the cylinder with the hide, and means for moving said guard into and from operative position.

7. In combination with a fleshing machine including a fleshing cylinder, means for receiving a hide to be fleshed and for feeding the same to the fleshing cylinder, means for moving the hide receiving and feeding means to and from the fleshin cylinder, a hide protecting guard dispose longitudinally of the cylinder, uides for receiving the opposite ends of the guard, a rotary shaft, and cam mechanism between the shaft and the guard for causing a movement of the guard to lie in advance of the fleshing roll when the hide receiving and feeding means are in inoperative position.

In testimony whereof I have signed my name to this specification.
